[Bug 598645] Re: Backlight off after resume from suspend (on lid-close only) on Compaq Mini 110c-1000

[Stenten]

** Description changed:

- Binary package hint: xserver-xorg-video-intel
+ === Problem ===
+ Just close the lid of my netbook and wait until it suspends.
+ Open the lid and wait for it to power up. The machine is running but no backlight. I can "see" that something is on the screen.
  
- The issue is simple:
- just close the lid of my netbook and wait until it suspends.
- open the lid and wait for it to power up. the machine is running but now backlight. I can "see" that something is on the screen.
+ === Workaround ===
  After digging through the forums I found a workaround: just change the brightness with Fn+F3 or Fn+F4.
+ 
+ === Upstream Testing ===
+ Fixed on 2.6.35 6/15/10 daily/current Mainline build.
+ 
+ === Debugging ===
+ Suspending from console using pm-suspend works normally (backlight comes back on after resume).
+ 
+ === Additional Information ===
  The strange thing is that this didn't happen with 9.10 or 10.4 (updated from 9.10). I had to reinstall the machine (broken HDD) and this started to happen.
  I saw similar reports but not quite the same.

+ If the lid-close setting is changed to "Black screen", the lid can be closed and re-opened and the backlight comes back on at as expected.
